Overview
SM5301BS 3-channel Video Buffer with Built-in Wideband Filters with Filter Through Function OVERVIEW The SM5301BS is a video filter LSI with buffered outputs for VESA-standard ATSC digital TV.
The filter employs a 5-order Butterworth lowpass filter configuration.
The filter characteristics have been optimized for minimal overshoot and flat group delay, it has a variable cutoff frequency and guaranteed output buffer-stage channel gain difference and phase difference values.
It has also filter through mode.
FEATURES I Supply voltage: 5V ± 10% I VESA-standard ATSC digital TV RGB/YUV video filters I RGB/YUV switching multiplexer function I Synctip clamp input I 0dB, 6dB gain switching function (input-to-output AC signal gain) I Channel-to-channel gain difference: 0.
5dB (± 5% supply voltage variation) I Channel-to-channel phase difference: 3.
5 degree I Output signal harmonic distortion (all channels): 1.
5% I Cutoff frequency: 5 to 37MHz variable I Filter through mode (passband frequency is 46MHz, when gain is 6dB) I Package: 28-pin HSOP (Pb free) APPLICATIONS I Set-top boxes I Digital television I DVD players PINOUT (Top view) GINA/UINA 1 GSG1 2 GINB/UINB 3 NC 4 BINA/VINA 5 GSB1 6 BINB/VINB 7 GND NC 8 DISABLE 9 GND3 10 BOUT/VOUT 11 VCC3 12 GND2 13 GOUT/UOUT 14 28 NC 27 RINB/YINB 26 GSR1 25 RINA/YINA 24 VCC4 23 THROUGH 22 MUXSEL GND 21 VFC 20 RFC 19 GND4 18 VCC1 17 ROUT/YOUT 16 GND1 15 VCC2 ORDERING INFORMATION Device SM5301BS Package 28-pin HSOP PACKAGE DIMENSIONS (Unit: mm) 0.
